As long as you're trying to do it on the cheap, I figure I can ask this question...Does the single spacer serve any purpose that 6 small individual spacers wouldn't? Can't see that it does other than make it less fiddly to assemble.

Individual spacers would be super easy to part off from a bit of Al. tubing with any lathe, heck, you could even use the lamest of all methods, spin tubing in a drill and part it off with a fixed hack saw blade.

ACtually, with the forces on braking you really should have one piece. See, instead of each bolt carrying it's own load and being allowed to flex, that ring connects them all and makes them stronger.

I'm not 100% certain how much it will flex but I'm fairly certain if it was OK to do that, the manu and engineers would have done that already to save a buck.

Well, hell, it's just Grant's bike: the front wheel is hardly ever on the ground, anyway...

Grant, don't let these people talk you into something stupid. I got your back. We need to get your example near my measuring tools (leave it alone bluuu ) so that I can get some magic done. I have some blackmail on a friend of mine, so we can get your spacers made.

I wouldn't do it the way I suggested either...having said that it is functionally equivalent and would be safe. To redkat60's point, the spacers have to have enough face area that the bolts see only shear and not bending. As far as sharing the load the rotor itself takes care of that.

No one mentioned the biggest potential issue with doing it with individual spacers, they have to all be very very close to the same length or it's just like a warped rotor.

Yes, I am a mechanical engineer who has done stress analysis for a long time
Yes, I am too lazy to make a model and run FEA to prove it

Trust me, I'm from the government.

I have seen what you have access to.

Grant, get this guy your shit ASAP and I guarantee you he will make you something worthy of being on the space shuttle.
